He-Ne Lab Laser 0.5 mW / Class II
Economically priced, full-size helium neon lab laser

Industrial Fiber Optics' CT Series of lasers are the most popular line of lasers used in middle and high schools in the United States. Designed for education, and featuring a bright blue transparent enclosure, their attractive looks invite students to participate and explore in optical and laser technology while seeing the laser's internal "working" components. With a complete set of features and long warranty, it is a product that is hard to surpass.

The IF HN05 is a basic helium-neon CDRH Class II-rated laser. It is useful in most educational curricula as a beginning tool for exploring/experimenting in laser and optical technology. It is the lowest powered and most economical laser we offer (.5 mW of laser power is adequate for most basic optical experiments as long as there is not bright light in the room.)

CT Series lasers were specifically designed for use in education. They are not an engineering product or design being sold for educational purposes. From the initial concept, everything about the attractive, safe design was intended to interest students in technology. It includes safety features such as 110-VAC-to-low-voltage power adapters, tamper-resistant screws, impact-resistant acrylic enclosure, easily locatable bright red laser shutter, bright and very durable nickel-plated laser aperture, industry-standard electrical connections and tripod mount.

All manufacturers of lasers used in the United States, must conform to regulations administered by the Center for Devices and Radiological Health (CDRH), a branch of the U.S. Department of Health and Human Services. CDRH categorizes lasers as follows:

 Class 1

A laser or laser system which does not present a hazard to skin or eyes for any wavelength or exposure time. Exposure varies with wavelength. For ultraviolet, .2 to .4m exposure is less than from .8 or near IR, the exposure is < 200w. Consult CDRH regulations for specific information.

 Class 2

Any visible laser with an output less than 1 mW of power. Warning label requirements yellow caution label stating maximum output of 1 mW. Generally used as classroom lab lasers, supermarket scanners and laser pointers.

 Class 3a

Any visible laser with an output over 1 mW of power with a maximum output of 5 mW of power. Warning label requirements red danger label stating maximum output of 5 mW. Also used as classroom lab lasers, in holography, laser pointers, leveling instruments, measuring devices and alignment equipment.

 Class 3b

Any laser with an output over 5 mW of power with a maximum output of 500 mW of power and all invisible lasers with an output up to 400 mW. Warning label requirements red danger label stating maximum output. These lasers also require a key switch for operation and a 3.5-second delay when the laser is turned on. Used in many of the same applications as the Class IIIa when more power is required.

 Class 4

Any laser with an output over 500 mW of power. Warning label requirements red danger label stating maximum output. These lasers are primarily used in industrial applications such as tooling, machining, cutting and welding. Most medical laser applications also require these high-powered lasers.
